These brass rotary shoe valves are made of a special brass alloy (DZR) allowing use in heating and cooling systems, for both mixing and diverting applications. Valves are available from ½” to 2” sizes with internal threads. Note: These are not tight shut-off valves.
This range of Safety Switches in lower case is for use in the event of fire or other emergency. Usually located at exits to gas plant rooms, units are key operated with a 2 or 3-position latching switch. It is ideal for use in situations where a glass window would pose a hazard, i.e. food preparation areas, schools etc.
The LL-C are designed to give savings over uncontrolled lighting whilst retaining an ease of installation and configuration. A passive infra-red detector monitors occupancy through moving body heat and a photo-sensitive device monitors light level. This will ensure that lighting is only switched on when the area covered is occupied and the light level is too low for normal working conditions.
Using passive infra-red detection, the OC-C-LVN occupancy detector monitors occupation through moving body heat and upon detection the internal SPDT relay activates. The OC-C-LVN is for flush mounting through a false ceiling using the clips provided.
This is a concept for total environmental sensing in a single space or plant housing. Each sensor measures a predefined selection of variables. All option outputs are available via BACnet MS/TP or ModBus RT. The databus type is user-selectable. If your application has specific requirements, this sensor can be tailored with a wide range of options.
The BACnet Internet of Things Gateway offers all you would expect from a high end Explorer product and more. It not only automatically discovers BACnet IP and BACnet MS/TP networks, but with Monitor View and Historian features, device data points can be precisely tracked and logged for analysis. Additionally it also acts as a Wifi Access Point for remote access from any mobile device without user restrictions. Cellular data (SIM card required) is an option.
The PM-EM210 is a compact energy meter that has a removable front LCD display that allows it to be either DIN-rail or panel mounted. The energy meter is designed for active and reactive energy metering. All operations, including programming and viewing up to seven display pages are performed using the two push buttons on the detachable display. It is possible to block the access to programming by means of a trimmer position on the rear of the display. Standard meters are non-MID. For billing use, add annex -B+D option.
